According to a report from Business Insider, Samsung Mobile’s Chief Marketing Officer Todd Pendleton has left the company. Pendleton notified colleagues of his departure, effective in April, earlier this week. Neither Samsung nor Pendleton have offered a statement on the shake-up, and details regarding reasoning are sparse at this point.

At Samsung Mobile, Pendleton was responsible for leading development of the company’s “Next Big Thing” marketing campaign. The campaign is said to have been the leading cause of Samsung’s quick rise to dominance when it launched the Galaxy S3. The campaign heavily mocked Apple and led to the Galaxy S3 becoming the top-selling smartphone that year.
